WEBA prion disease is a type of proteopathy, or disease of structurally abnormal proteins. In humans, prions are believed to be the cause of Creutzfeldt–Jakob disease (CJD), its variant (vCJD), Gerstmann–Sträussler–Scheinker syndrome (GSS), fatal familial insomnia (FFI), and kuru.

Prion Disease: What It Is, Types, Causes, Symptoms & Treatment
WEBPrion disease happens when normal proteins in your brain turn into abnormal proteins known as prions (pronounced “PREE-ons”). Prion disease (sometimes called transmissible spongiform encephalopathy) causes brain damage that leads to dementia. These symptoms develop suddenly and worsen quickly. definition
WEBA prion is a type of protein that can trigger normal proteins in the brain to fold abnormally. Prion diseases can affect both humans and animals and are sometimes spread to humans by infected meat products. The most common form of prion disease that affects humans is Creutzfeldt-Jakob disease (CJD). Prion diseases are rare.
